NASA gave its final go-ahead on Friday to billionaire entrepreneur Elon Musk’s SpaceX company to conduct its first unmanned test flight of a newly designed crew capsule to the International Space Station on March 2. The approval cleared a key hurdle for SpaceX in its quest to help NASA revive America’s human spaceflight program, stalled since space shuttle missions came to an end in 2011.

SpaceX is moving quickly toward one of the most important launches in its 17-year existence: The first launch of Crew Dragon, a spaceship that Elon Musk's aerospace company designed to fly NASA astronauts into orbit. Crew Dragon is part of NASA's roughly $8 billion Commercial Crew Program, which was created to restore the agency's ability to launch people to the International Space Station. (NASA retired its space shuttle program in July 2011, and has been sending astronauts on Russian Soyuz spacecraft since then.)

3D printing has been used in the medical industry before, where we have seen the tech used to 3D print cartilage and skull implants. Now it seems that Russian researcher Oleg Kononenko has successfully managed to 3D print living tissue, but here’s the kicker: not only is Kononenko a researcher, but he is a cosmonaut as well, and this 3D printing was actually done in space.

Scientists conduct various types of experiments to find the pros and cons of different things on human body. Before conducting on humans scientists conduct their experiments on animals. But this strategy is not applicable while conducting space study. NASA and different space agencies send astronauts to study the effect of space on the human body. NASA conducted such experiment in 2015.

Astronauts—they’re just like us. Last week, the International Space Station was plagued by a leaky toilet. The crew onboard had to put their plumbers’ hats on and get to work repairing the system as gallons of water spilled weightlessly out into the spacecraft, 250 miles above the surface of the earth. Yeeeesh, that’s rough.

This educational documentary video goes inside the International Space Station (ISS) which is a space station in low Earth orbit. First launched into orbit in 1998, and now its the largest artificial body in orbit and can often be seen with the human naked eye. The crew can only stay in space orbit for several months maximum, then then must return to Earth. The ISS interior consists of pressurized modules, external trusses, solar arrays, and other components.

Today at 2:10 am ET, the International Space Station began its 100,000 tour around this blue-and-green globe we call home. Travels at a blazing 17,500 mph, ISS finished that historic achievement only 92 minutes later. In its 18-year lifespan, the station has traversed about 2,643,342,240 miles, more than 28 times the distance of the earth to the sun. Damn, ISS.

NASA is dead set on leaving Low-Earth Orbit to go to the moon, Mars and other farther destinations. That means extending the space station's funding beyond 2024 is out of the question. Now, NASA Deputy Associate Administrator Bill Hill has revealed what the agency wants to do with the ISS once astronauts move out. Instead of deorbiting it and sinking it into the ocean or breaking it apart to sell piece by piece, it apparently wants to hand the spacecraft over to a private corporation.

The clock is ticking on NASA’s time aboard the International Space Station (ISS). The agency has set its sights on targets deeper into space, and the station itself, at least on NASA’s side, is unlikely to last beyond a decade without a significant overhaul. But that doesn’t mean it’s the end for the ISS. Back in August, Bill Hill, NASA deputy associate administrator for exploration systems development, suggested that the ISS’ future lay with the private sector.

NASA needs help solving one of its most basic — and critical — problems, and the winning idea could land you $30,000. The problem is this: During launch and entry, astronauts are locked into their suits, unable to access any part of their body for hours. As a result, if they need to urination, defecate or are menstruating, they must do so in special adult diapers.

Russian scientists are planning to install and operate a 3D bioprinter aboard the International Space Station, according to an official source. They believe that microgravity conditions could actually improve the bioprinting process.

Two Russian cosmonauts and a US astronaut touched down safely in central Kazakhstan Monday following a 173-day mission aboard the International Space Station (ISS). "Touchdown confirmed," said a commentator on NASA Television, describing it as a "textbook" landing. NASA astronaut Shane Kimbrough was accompanied by Russian space agency cosmonauts Sergei Ryzhikov and Andrei Borisenko in the earthbound Soyuz MS-02.

A team of researchers wants to ‘bake were nobody baked before’. Sometime in 2018, a microgravity oven is slated for launch to the International Space Station where it will bake the first space-grade bread in history. As anything on the International Space Station, this won’t be your regular bread. Designed and inspected from all scientific angles, the space bread will not only be filling and fresh, but also safe for the special environment.

The International Space Station is considered to be the largest spacecraft ever built. It was first launched in 1998 and continuously occupied by astronauts since 2000. The assembly is of the ISS has been ongoing for 20 years, making it possibly the one of the largest space projects today. Here is a look at some of the interesting facts and numbers about the International Space Station.

Astronaut Peggy Whitson returned to Earth late Saturday, wrapping up a record-breaking flight that catapulted her to first place for U.S. space endurance. Whitson's 665 days off the planet — 288 days on this mission alone — exceeds that of any other American and any other woman worldwide. She checked out of the International Space Station just hours earlier, along with another American and a Russian. Their Soyuz capsule landed in Kazakhstan shortly after sunrise Sunday — Saturday night back in the U.S.

The International Space Station (ISS) crew had to hide in a special shelter during a massive solar flare, a nuclear scientist said. The sun produced several huge solar flares last week, one of which was the strongest observed in a decade.

In a major space policy decision, Russia will promise to join a NASA-led effort to build an international human outpost in the vicinity of the Moon. Russian industry sources told Popular Mechanics that the head of Roscosmos State Corporation, Igor Komarov, is expected to announce the news next week during a meeting with other space agencies at the 68th International Astronautical Congress in Adelaide, Australia.

You can always count on the crew of the International Space Station to harness technology to bring us up to the heavens with them. Back in July, they uploaded enough footage to map the entire station out on Google Streetview. Today, the crew uploaded the first spacewalk recorded in 360-degree video. Immerse yourself in footage of mankind maintaining its farthest outpost at the border of space.

NASA astronaut Scott Kelly spent a year in space. His recollections of this unprecedented test of human endurance, and the physical toll it took, raise questions about the likelihood of future travel to Mars.

A surprising number of people believe we already have proof aliens exist. But it’s very rare when that segment of the population overlaps with the segment that’s actually been to outer space. And yet, on Monday, Anton Shkaplerov, a Russian cosmonaut who has already spent two stints aboard the International Space Station and is gearing up for a third mission to launch on Dec. 18, told Russian state media that scientists have found living bacteria sitting on the exterior of the Russian segment of the ISS. He claims the bacteria is not from Earth—it’s extraterrestrial in origin.

Being able to identify microbes in real time aboard the International Space Station, without having to send them back to Earth for identification first, would be revolutionary for the world of microbiology and space exploration. The Genes in Space-3 team turned that possibility into a reality this year, when it completed the first-ever sample-to-sequence process entirely aboard the space station.

A Japanese astronaut has apologised for wrongly stating he has grown 9cm (3.5in) since arriving at the International Space Station (ISS) just over three weeks ago. Norishige Kanai said in fact he grew by 2cm, blaming "a measurement mistake". "I'm very sorry for tweeting out such fake news," he tweeted in Japanese. His original incorrect claim sparked global fascination among social media users. Astronauts grow an average of between 2-5cm in space.

The US astronaut Jeanette Epps has been removed from her upcoming mission to the International Space Station (ISS) just months before launch. Dr Epps was to have been the first African-American astronaut assigned to the space station crew. She would have flown aboard a Russian Soyuz flight in June but is being replaced by another astronaut.

The International Space Station is considered a shining example of the uniting power of science. Since the late 1980s, countries that were once at war with each other have worked together to further scientific research applied both on Earth and in space. But in its proposed 2019 budget released last month, the United States, the biggest financial backer of the ISS, indicated it will stop funding the station in 2025, and instead look at transitioning the orbiting laboratory to commercial enterprises.

The International Space Station has hosted more than 230 astronauts over the years, and now it’s set to host its first floating robotic head. A ball-shaped robot known as CIMON — that’s short for Crew Interactive Mobile Companion — will join German astronaut Alex Gerst when he and his crewmates rocket to the ISS this June. Roughly the size of a medicine ball and weighing about 11 pounds, CIMON is designed to accompany and assist Gerst and his crewmates as they move about the ISS.

Spending a year in space not only changes your outlook, it transforms your genes. Preliminary results from NASA's Twins Study reveal that 7% of astronaut Scott Kelly's genes did not return to normal after his return to Earth two years ago. The study looks at what happened to Kelly before, during and after he spent one year aboard the International Space Station through an extensive comparison with his identical twin, Mark, who remained on Earth.

Three new crew members of the International Space Station have successfully arrived in low-Earth orbit. The NASA astronauts — two Americans and one Russian — will serve as flight engineers for ISS Expedition 55/56 for five months. After a two-day journey, the Soyuz MS-08/54S space capsule that launched from Russia's launch complex in Baikonur, Kazakhstan on March 21, has successfully docked at the space station at 10:40 p.m., Friday.

Incredible images show SpaceX’s Falcon 9 rocket blasting the firm’s Dragon spacecraft towards the International Space Station to deliver human sperm for a NASA experiment. The space agency plans to test how well human and bull sperm functions in space after previous tests on sea urchin semen suggested microgravity allowed it to activate more quickly.

Sperm is objectively pretty strange here on Earth, so imagine how it looks and acts in microgravity. A NASA scientist tells Inverse that’s exactly what astronauts on board the International Space Station (ISS) will be doing over the next few months.

The Trump Administration’s plan to hand the International Space Station off to the private sector by 2025 probably won’t work, says a government auditor. It’s unlikely that any commercial companies will be able to take on the enormous costs of operating the ISS within the next six years, the auditor said.
